Abstract
The subject matter of this specification can be embodied in, among other things, a rotary vane actuator that includes a rotor assembly including a rotor hub. The rotor hub has a first and second vane assembly disposed radially on the rotor hub. Continuous seals are disposed in continuous seal grooves along pathways provided along the vanes. A stator housing having a central chamber includes an interior surface adapted to receive the rotor assembly, the interior surface is adapted to continuously contact the first continuous seal and the second continuous seal when the rotor assembly is rotated inside of the central chamber. The vane assemblies and the stator housing define pressure chambers inside of the central chamber.
